Wing rib

The wing ribs are structural components within the wing. Together with the longerons, they form the frame for the wing skin. Wing ribs are predominantly manufactured from wrought aluminium alloys.

These are light, have a high load-bearing capacity and are extremely robust. This applies in particular for new generations such as the 2050 aluminium-lithium alloy. In order to enable this alloy to be machined successfully, the machine, tool, processes and milling strategies must be designed to perfectly suit the workpiece and the alloy. Walter high-performance solutions for HPC and HSM aluminium machining meet the highest requirements for quality and process reliability, whether working with indexable insert tools, carbide tools or PCD tools.
